Don’t filter candidates in pinyin mode
Don’t filter candidates in pinyin mode

I may change that again later, but currently the format of the
candidate tuples in pinyin mode is different from the format in
non-pinyin mode which makes this filtering fail. Therefore, pinyin
mode would not work at all at the moment if Chinese mode 2 or 3 is
selected.
